Difference 1: Safety
At present, most of the ordinary electric wheelchairs on the market have only one controller, two motors and four wheels. Although they can be driven by an electric motor on the ground or convenient for the elderly, they cannot climb stairs. When they encounter stairs or need to go upstairs, they can do nothing. Many elderly people are inflexible and can't go up and down the stairs alone. Even if they go up and down the stairs, they have no power to carry dozens of kilograms of electric wheelchairs up the stairs.
The electric ladder wheelchair can not only drive on the flat ground, but also be equipped with track for ladder. It can switch between flat walking and stair climbing functions. When you need to walk on the flat ground, you can fold it up and move like an electric motor. When you meet the stairs, you can put down your tracks and climb them like a small tank.
Although it seems simple, the consideration of safety cannot be ignored. The general control ability of the elderly is relatively weak. When climbing stairs, the steps are steep and the space is narrow, which is a huge security risk for the elderly. To make a very safe product, it is not only necessary to simply add a track on the basis of the electric wheelchair, but also necessary to carefully design, carefully consider the actual situation of various use environments of each step, as well as the problems and obstacles that different elderly people may encounter in the operation process. In addition, it needs to be easy to operate without security risks. It often needs several years of design, development and testing to produce the final mature and reliable electric climbing wheelchair.
In recent years, it is not uncommon for the elderly to slide up and down stairs. This also shows that the demand of electric ladder wheelchair and the safety requirements of the elderly are very high! The design of ordinary electric wheelchair does not need to consider these problems, only the basic safety of speed and brake, which is much simpler.
Difference 2: low output
The industrial chain of ordinary electric wheelchair or electric vehicle is relatively mature, especially the ordinary electric vehicle. China's annual output is often tens of millions of sets. In addition to the export volume, the annual output is basically over 100 million. Such a huge turnover also makes the whole industrial chain very mature. From parts to vehicle factories, the production cost is extremely low, and the terminal sales price is relatively low.
Even for ordinary electric wheelchairs, with the development of China's market for many years and the increase of the elderly population, the industrial chain is gradually improving, with an annual shipment of nearly 10 million units and a production value of several billion, which also makes the cost drop a lot. However, there are only a few manufacturing enterprises in the field of electric climbing wheelchair in the world, no more than 100. Most of them are only engaged in electric wheelchairs. Generally speaking, they have other main businesses to produce other products. The annual output of electric climbing wheelchair in China is tens of thousands, which belongs to the industry with very low output. Due to the low overall output, the supporting industry chain will not be particularly mature, which will increase the cost of parts, production, operation, maintenance and other links, resulting in the low retail price of electric climbing wheelchair terminal, which is one of the important reasons.
